A label at the end of a chain
The programme, player, operating system and output connection each contribute information to the sound you hear. A receiver sees the signal sent to it. It cannot automatically reveal every earlier decision, including a player's mixing or conversion. That is why an output badge is useful evidence but an incomplete programme specification.
Apple documents a continuous audio connection option using Dolby MAT and notes a possible Atmos indication on older receivers even when the programme is stereo. This is a specific reason to avoid treating the front-panel word as proof of an Atmos source. Other equipment may behave differently.
Look for two independent observations
First, inspect the programme's available audio tracks in the app. Record the exact selected track and whether the catalogue offers a format label. Second, inspect the receiver's input and processing information if its manual explains those screens. An input format and a listening mode may appear in different places and answer different questions.
Do not switch to an unrelated demonstration clip and conclude that the original programme had the same specification. A successful demonstration establishes that one supplied sample can produce a result through the current chain. It does not audit an entire catalogue.
Should you change the connection setting?
Change it only for an identifiable need, such as restoring useful format reporting or testing receiver-specific behaviour. Note the original value and compare the same track before and after. Be alert to start-of-playback behaviour and other supported formats. A different badge alone does not prove a listening improvement.
Apple TV's available controls vary with equipment and software. Consult the exact audio setting description rather than copying a screenshot from an older release. Keep changes reversible and avoid simultaneously changing the app track, receiver listening mode and output format.
Describe what you know
A sound report might say: the app lists a stereo track, the receiver displays Atmos with the continuous connection enabled, and dialogue is audible from the expected speakers. That records a discrepancy without accusing the service of supplying a false track. If sound is missing, add which speakers or passages are affected.
No label in this article establishes an IPTV service's audio catalogue. Ask the provider for the relevant programme and device specification where necessary. Hardware output capability, app support and actual supplied tracks must all align.

Scope notes distinguish published documentation, supplied information and editorial methods. They do not report a hands-on service test.
